Title: Manufacturing method for capacitor structure of DRAM component on semiconductor substrate
Inventor: LIN DA-CHENG
IPC: H01L27/108
Filed: 1998-08-14
Granted: 2000-03-01
Abstract: The invention relates to a kind of capacitor structure of DRAM and employing hemisphere grains (HSG) silicon layer as the upper layer of node storage electrode to achieve increasing surface area. The method employs mixed buffer layer of undoped and lightly doped density amorphous silicon layer which is allocated above the highly doped density amorphous silicon layer and then depositing HSG silicon crystal seeds. Then, the first annealing process employs consumption of HSG silicon crystal seeds and consumption of mixed buffer layer of undoped and lightly doped amorphous silicon layer and allowing the undoped HSG silicon crystal forming on lower highly doped density amorphous silicon layer. The second annealing process then allows doped crud reaching undoped HSG silicon crystal layer from lower highly doped density amorphous silicon layer and results in doped HSG silicon layer. Forming patterns or applying chemical mechanical polishing on the doped HSG silicon layer and highly doped amorphous silicon layer results in the forming of storage node electrode. By employing the mixed buffer layer, it allows the growth of undoped HSG silicon layer so that it can reach the maximum uniformity and roughness of HSG silicon and results in the formation of doped HSG silicon layer when the undoped HSG silicon crystal layer is under annealing.  The capacitor void is reduced compared to undoped HSG silicon crystal reference object.

Title: Write-in driver circuit
Inventor: SUSHIHARA KOJI
IPC: G11B5/012
Filed: 1998-09-22
Granted: 2002-02-21
Abstract: The purpose of the present invention is to provide a write-in driver circuit. The write-in driver circuit is used to switch the direction of write-in current that flows to the magnetic head and so on having the inductance component. In order to switch the write-in current at high speed, four NPN transistors are used to form an H-type bridge circuit. In addition, four switch apparatus are used to control the base potentials of these four NPN transistors. Furthermore, when the write-in current flowing to the magnetic head is switched, the voltage difference generated in between both ends of the magnetic head is increased by installing two switch apparatus that decrease rapidly the base potentials of the transistors, which make two NPN transistors at the power source side cut off.

Title: Ringer for satellite user terminals
Inventor: EDGAR CLEMENT B III
IPC: H04B7/185
Filed: 2000-09-15
Granted: 2002-10-01
Abstract: An apparatus, system, method, and computer program product for providing a flexible ringer for multiple deskset phones. A controller detects a flag message that precedes an incoming telephone call, and selects one or more frequencies based on a local expectation of a ringing telephone at the geographic location, or according to a user preference. A digital signal processor (DSP) generates a digital ringer signal based the selected frequencies. An audio codec converts the digital ringer signal to an analog ringer signal and sends the analog ringer signal to multiple deskset phones using a receive cable. The analog ringer signal is amplified to drive a speaker that converts the analog ringer signal into an audible ringer sound at each deskset phone. The audible ringer sound can be customized for multiple geographic locations by modifying the selected frequencies used in the digital ringer signal. In one embodiment, a user selects the current geographic location from a menu of multiple geographic locations, where each geographic location in the menu is assigned the requisite frequencies to meet the local expectation of a ringing telephone. Alternatively, a user selects from a non-geographic specific list of preselected frequencies typically found useful by users.
